Forest communities in southwestern Ghana use 70 species of medicinal timber to deal with as much as 83 illnesses, in line with a current examine.These vegetation comprise excessive ranges of bioactive compounds with pharmacological advantages, however many are additionally threatened by components together with overharvesting and agricultural enlargement within the space that drives large-scale deforestation.Due to a scarcity of entry to Western medication and cultural perceptions, conventional medication is the first supply of remedy for a lot of forest-fringe communities.The authors say government-led conservation applications and preserving conventional data is vital to conserving these medicinal tree species.
Rural communities in southwestern Ghana missing entry to standard medication are utilizing dozens of medicinal tree species to deal with as much as 83 illnesses, in line with a brand new examine. However, many of those tree species are additionally threatened by components together with overharvesting and agricultural enlargement that drives deforestation within the space, the examine authors say.
The examine, printed within the journal Heliyon, discovered that the communities on the fringes of the Asukese Forest Reserve and Amama Shelterbelt Forest Reserve use 70 species of medicinal timber from 33 taxonomic households. The high 5 pharmacological results they attribute to those timber are anti-inflammatory, anti-malarial, anti-microbial, anti-bacterial, and reproductive boosting properties.
“Herbal medication is just like the ‘first help’ of rural communities and the one help in some distant areas,” examine co-author Michael Asigbaase, a lecturer within the Department of Forest Sciences at Ghana’s University of Energy and Natural Resources. “There are herbalists in all communities. In truth, in some circumstances, they’ve been in a position to assist individuals who couldn’t discover assist through clinics and hospitals.”
The examine authors interviewed 88 respondents from 4 communities, together with the Indigenous Akan-Bono individuals and northern tribes just like the Kusaasi and Waala to grasp their use of medicinal timber within the area. The findings had been evaluated utilizing 5 parameters, together with an Indigenous data index that assessed neighborhood data of plant properties, therapeutic results, varieties and unintended effects. The remainder of the parameters checked out how typically medicinal properties had been cited in scientific literature, the species and vegetation’ half worth, and their use inside households.
For distant native communities in Ghana, medicinal timber are the first supply of remedy, on condition that they’re simply accessible to communities residing on the fringes of forests. Despite current advances in Western standard medication, the dependence on conventional medication in lots of nations in Africa is as a result of comparatively excessive value of the previous, restricted well being service protection and variety of well being professionals, and the cultural normalization of conventional medication.
“Many communities in Ghana understand natural medicines to be simpler than orthodox [Western] medication as a result of they’re obtainable, inexpensive, and there’s shared data on how one can put together and administer them,” Asigbaase informed Mongabay. Traditional healers in Ghana present an estimated 70% of well being care utilizing numerous medicinal species. Ghanaian tribes consequently collected conventional medication data of a mixed 1,360 species of medicinal vegetation for his or her main well being care wants.
According to the examine, members who had been widowed had extra data of medicinal vegetation in comparison with respondents who had been married or single. This was as a result of they’ve numerous dependents or have skilled the lack of a partner, the authors say, which is related to restricted earnings or entry to assets for Western medication.
Azadirachta indica, generally generally known as the neem tree, was essentially the most ceaselessly cited medicinal tree species.
“Plant species of the Fabaceae, Apocynaceae, Arecaceae [families] and their intently associated households have typically been reported to comprise excessive ranges of bioactive compounds with pharmacological worth,” Asigbaase stated.
“Consistent with our findings, some research have reported ethnobotanical data on using varied timber for the remedy of human, plant, and animal illnesses.”

A remedy in danger
Despite their extensively acknowledged medicinal worth, these timber are additionally utilized by neighborhood members for different functions. These embody making charcoal for gas and as timber for building and carpentry — makes use of that pose a risk to the conservation of the tree species. Wider threats like agricultural enlargement, logging, mining, urbanization and local weather change additionally contribute to the lack of medicinal tree species by deforestation, the examine famous.
According to the United Nations Development Programme, the present deforestation and forest degradation charge in Ghana is 135,000 hectares (333,600 acres) yearly. Another examine by Asigbaase and a number of other colleagues concerned within the Heliyon paper, and likewise performed close to the Asukese and Amama forest reserves, reveals that seven of the cited medicinal plant species are susceptible to extinction.
Overharvesting of those vegetation, that are primarily sourced from the wild, is among the many high drivers of the lack of medicinal vegetation within the examine space. According to the notion of residents interviewed for that examine, medicinal vegetation will grow to be domestically extinct in a decade.
The lack of these species means the erasure of their conventional data, spirituality, and historical past, say researchers of one other examine on Ghana’s ethnobotanical traditions. According to Bismark Ofosu-Bamfo, a lecturer in ecology on the University of Energy and Natural Resources, there are robust ties between the timber and tradition in most tribes throughout Ghana.
“Some names of cities like Odumase could actually [mean] ‘beneath the Odum tree’ [Milicia excelsa]. A reputation like Onyina, which is a surname and likewise an appellation for a male born on Thursday [Yaw Onyina], is identical because the native title for Ceiba pentandra,” he stated.

Ofosu-Bamfo stated sustainable harvesting of natural medication is a key problem because the demand for timber, just like the bark of Khaya species, also called African mahogany, is excessive, primarily from producers of natural bitters. The demand for vegetation like Khaya grandifoliola, studied for the remedy of gastric ulcers, typically results in felling and debarking of entire timber.
“Conservation dedication from customers of natural medication at an area to industrial scale is required,” Ofosu-Bamfo stated. “Alternatives to timber could exist in intently associated woody climbers [like lianas], a few of that are in the identical households because the timber used for a similar medical circumstances.”
In 1975, the federal government established the Centre for Scientific Research into Plant Medicine (CSRPM), later renamed the Centre for Plant Medicine Research (CPMR). According to Asigbaase and colleagues, the federal government realizes the significance of conventional medication in Ghanaian society.
“The actions of the CPMR and different scientific research confirming the efficacy of such natural cures have additional promoted and elevated the utilization of natural medicines in Ghana,” their examine says.
One approach wherein communities within the examine space are attempting to preserve medicinal timber is thru government-led forest restoration and safety applications that concentrate on frequent forest fires within the area. The impacts of those applications are but to be evaluated.
“Local communities play a vital position in preliminary firefighting and help in early detection, boundary clearing to comprise the fireplace, and the planting of timber,” Asigbaase stated.
“The communities additionally take part within the Modified Taungya System [MTS], which is an revolutionary forest restoration device. It is an agroforestry system the place members are given parts of degraded forest lands to domesticate crops till the cover of the timber closes.”
Contrary to the findings of comparable research that present conventional plant data diminishing throughout generations, the authors discovered comparable ranges of ethnobotanical data throughout completely different ages, genders, religions and academic ranges. This suggests an efficient switch of information amongst people in native communities, which might play a job within the conservation of species.
“This switch of ethnobotanical data has been attainable by parental coaching and neighborhood data sharing through word-of-mouth suggestions,” Asigbaase stated.
“There is a saying among the many native communities that may be translated as, ‘If you might be sick, you shouldn’t hold quiet,’” he added. “Thus, neighborhood [members] discover options to their well being issues by sharing their gathered ethnobotanical data.”
